Having problems with my Eberspacher D2.

It was fitted to the van when I bought it but not wired in, which I did yesterday. Long story short...it ran ok yesterday, when I did a second check after completing the final wiring it sounded strange (like a wonky fan but I know it was serviced before fitting byt theprevious owner and not used since) and now it won't start. I can just hear the pump I think trying to turn over and gives up after approx 5-10 trys.

As soon as I pulled away in the van after shutting down the heater the fuel reserve light came on so therefore I'm expecting the system needs bleeding or resetting.

Any ideas or hints anyone, sound right to you?

Probably just needs bleeding.
When i installed mine i used a cordless drill battery to bleed.
Remove the end of the fuel line going into the heater.
Use a cordless battery to power the pump until fuel comes out of the line.( pump should be under the van)
(You need to intermitently contact the power to the pump as each contact only give one cycle)

hope this helps

Cheers, I'll try that when the weather improves/I can get access to the underside of the van. My bloody drill battery is a 7.2v piece of rubbish, so I'll have to try something else:confused:

disconnect the fuel feed at the eber.
disconnect the fuel pump harness near the heater
connect pump Ground to chassis
extend the positive feed to the pump long enough to get to battery.

now tap the positive feed ON-OFF max 1sec ON and 1sec OFF do this until your getting fuel out of the eber fuel line.
(dont permanently short the pump ON or short it on whilst connected to the eber)

reconnect fuel feed to eber.
remove all temp harness mods used to bleed.
reconnect pump harness to eber

turn on eber as normal..

When I fitted mine to the splitty I just switched it on and let it run through its cycle until the error light flashed (this is on a Webasto) and then tried again. It took about 5 cycles to fire. The dip pipe is deliberately too short so it sucks air before it empties the fuel tank. Just ensure the pump is installed it the correct angle.

Tried running it a few times now but still nothing.

I haven't had a chance to attempt to bleed it but when I do turn it on it sounds as though a motor or fan is trying to rotate. Is this what it should sound like if it needs bleeding? Do these things seize or is it the air preventing the fuel pump from operating?

The fan should start at a slow speed then after a little while (20 seconds or so) the fuel pump will start to click away, if no fuel gets to the heater after a 10 seconds or so then it will shut itself down.
I think they can lock themselves out if this happens too many times, so i wouldnt keep trying to start it until you have reprimed the fuel line up to the heater.

Most Ebers will make 4 attempts to start and if starved of fuel they will then lock out on a fault code. The tapping the positive feed on the battery is the most straightforward method of bleeding so if that wont work then you are probably locked out.

To unlock the fault code you will need a Eber diagnostic unit to trace fault and then reset your unit. Most dealers charge you £30 for this and its about 5 mins work.

If you are near me you can use my diagnostic unit and I will reset it for you. Will cost you a 6 pack of Kit Kats though.

I am near J3 on the M3 if that helps.

The D2 heater goes through 2 start up cycles before it logs a fault. You should hear the pump ticking slow to start then speed up if it does not establish a flame it will stop and do a restart. If it still does not start after the restart it shuts down you have to turn it off for 5 mins then turn it back on again, to avoid waiting just disconect the positive feed for the heater either fuse or plug and refit then start again. They dont usually lockout they just log a fault 52 "safety time exceeded" in the fault code memory. They only lockout if about 5 different faults are logged.

It might be worth your while getting the documentation that is available from Eberspacher http://www.eberspacher.com/support-and-downloads/technical-documents.html that should tell you all that you wish to know.

By the way I wouldn't worry too much about the Eberspacher running your tank dry, they use so little fuel that it would take a while to use up what is in a tank if you parked before the low level light came on. Flat out and always on it would use about 6 litres in 24 hours and would probably have fried you into the bargin.

Finally bit the bullet and took it to an eber place near me today as I thought it was something more than an air lock.

It turns out that the unit has been installed upside down which apparently floods the glow plug in cold fuel. Any ideas?

Also the inlet pipe had been crushed somehow and then rubbed the inlet fan, so it was either sticking or had locked itself out as there was no air coming in to cool the unit (overheating)

Can't really figure out what could've crushed the inlet pipe as there's no signs of a strike from something. If the hole into the cabin is not big enough could the fan collapse the inlet pipe?

The specialist is talking big money as he thinks alot needs replacing but to be honest I'm gonna turn the unit on it's side, with advice from this forum if possibleT:, reconnect the hoses with a change of routing and see what happens :eek:

Thanks for all your advice, looks like it's all working well at the moment.

I took everything apart today, adapted the plate to a new position and length and re-installed at the correct angle. Bit of a pain to keep readjusting so the exhaust didn't rub or melt the plastic panel underneath but got there in the end. Really had to ensure the unit was happy as there's not much tolerance between the fan and the casing, which is also pretty flimsy IMO. Good job I took it all apart too as everything was loose, so it would've caused a stoppage at some point anyway.

Fingers crossed that it keeps working as I'm on a road trip to the Inner Hebrides next week for a spot of windsurfing:cool:

Thanks again T:
